Details: (optional)

While i was doing mythic Star Augur Etraeus with my guild, the server crashed (21:08 - 21:10). When i relogged back in, i lost my chest piece from Krosus Heroic, Finery of Azj'Aqir (138320), item level 895.
I am 100% certain i had it when we were fighting Star Augur before the crash, because as soon as i logged back in after the crash i noticed i had a different item equiped, and it wasn't transmogged like my chestpiece.
I checked the buyback tab just in case i maybe somehow (??????) sold it while repairing items earlier, but no, nothing in the buyback.
I sold 4 or 5 epic items i got from world quests before we started the raid, but not even those items were possible for buyback.
Checked the item recovery page, doesn't show the chest at all (or the epic items i sold either for that matter).

Exactly because of these potential things, i always kept every item up to 4 for each slot, in case stuff like this happens, and i checked my void storage in case i SOMEHOW forgot i put on something else and transmoged it, but didn't find the item in the void storage either.

Edit: Just to be precise, i kept every item i exchanged for a better item for up to 4 items in my void storage, so in case i somehow (like this) lose some of my items i could put on the first worst one i saved up when i changed it for the lost one. And i did that for about 4 5 items for each slot in my void storage, but the item wasn't there, so it was 100% on me when i was raiding before the crash.
